Specification of Letters Patent.

Patented June 9, 1914.

Application filed May 22, 1913. Serial No. 769,254.

To all whom it may concern:

Be it known that I, BYRON T. MILLS, acitizen of the United States,residing at Las Vegas, in the county of San Miguel and. State of NewMexico, have invented certain new and useful Improvements in PaperRacks; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements. in paper racks and particularlyto racks for use in connection with typewrit-ingmachines. for holdingcarbon paper, finished work and the like in convenient position to bereached by the operator.

Another object is to provide a rack of this character having improvedmeans for attaching the same to the base board of a typewriter wherebythe racks may be swung upwardly to permit the cover of the typewriter tobe placed in position over the same or which will permit the racks to bedisengaged from the base member to permit the cover to be placedthereon.

With these and other objects in view, the invention consists of certainnovel features of construction, and the combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 is a perspective view of atypewriter base board showing my improved racks applied thereto and inposition for use and illustrating in dotted lines the manner in whichsaid frames may be swung upwardly to permit the cover of the typewriterto be placed thereon; Fig. 2 is a detail vertical section of I a portionof the base board and a side View of a portion of one end of one of theracks showing the manner in which the latter is connected to the baseboard to be swung to operative and inoperative positions; Fig. 3 is avertical sectional view showing a side view of one lower corner andattaching member of the rackyFig. 4 is a detail perspective view of aportion of the base board showing the manner in which the same isnotched and recessed to receive the attaching members of the rack; Fig.5 is a similar view of one of the clips for holding the base engagingportions of the rack in pivotal connection with the base board; Fig. 6is a detail perspective view of a slightly modified construction of thepivotal connecting or attaching members of the rack; Fig. 7 is a viewsimilar to Fig. 2 illustrating in full and dotted lines a modifiedarrangement of the rack attaching mechanism whereby the racks arepivotally and detachably secured to the base member; Fig. 8 is a detailperspective view of a portion of the base member showing the manner inwhich the same is constructed to receive the rack attaching member shownin Fig. 7 Fig. 9 is a detail perspective view of a portion of one end ofthe rack frame and the attach.- ing member shown in Fig. 7; Fig. 10 is asimilar view of, a modified form of the rack attaching member shown inFig. 9. Fig. 11 is a similar view showing another modified constructionand arrangement of the parts shown in Fig. 9.

In the present embodiment of the invention wherein my improved racks areshown as applied to the base board or member B of a typewriting machine,1 denotes the racks which are in the form of wire frames the upper andlower side bars of which are bent to form series of inwardly projectingrectangular loops 2 which form a filling for the frames and prevent thepaper supported by the racks from falling therethrough. The end bars ofthe rack frames are extended downwardly below the lower cross barsthereof as at 3 and in the first form of the invention are bent upwardlyupon themselves to form combined stop and detent engaging lugs 4. Theends after being bent upwardly to form the lugs 4 are bent laterally atright angles to the ends of the frames and parallel to the lower crossbars thereof to form pintles 5 as clearly shown in Fig. 3 of thedrawings.

.It will be obvious that instead of bending the extended endsof the endbars upwardly and inwardly on the inner side of the extensions informing the lugs 4 and pintles 5 that said extended ends may be bentupwardly on the outer side of the extension in forming the lugs and bentoutwardly at right angles and in exactly the reverse directions fromthat shown in Fig. 3 to form the pintles5. It will also be obvious thatin addition to forming the lugs t and pintles 5 as shown in Fig. 3 ofthe drawings, I may secure to the outer side of the extensions 3 of theend bars a short rod 6 having a right angular inner end which issoldered or otherwise rigidly secured to the outer side of the extension3 as clearly shown in Fig.

6 of the drawing, said rod 6 forming an additional pintle projecting inthe reverse direction from the pintle 5 and providing an increasedbearing for the attaching mechanism of the racks.

The extended ends of the racks and the attaching mechanism whenconstructed as herein shown and described are adapted to be engaged withvertical notches 7 formed in the side edges of the base member near theends thereof as shown. The notches 7 communicate at their lower endswith inwardly extending recesses 8 formed in the lower side of the boardB, said recesses having inclined upper walls 9' as is clearly indicatedin Figs. 2 and 4 of the drawings.

In the side edges of the base member adjacent to one or both sides ofthe notches 7 are formed longitudinally disposed bearing grooves orrecesses 10 one of the ends of which communicate with the notches 7 asclearly shown in Figs. 3 and 4; of the drawings. It will be understoodthat the bearing grooves or recesses 10 are arranged to correspond withthe construction or arrangement of the pintles 5 and 6 and that when theattaching members of the racks are provided with both of the pi-ntles 5and 6 which project in opposite directions, the grooves or recesses 10will be formed on both sides of the notches 7 in the edges of the board.

The notches 7 and recesses 8 when formed in the manner described areadapted to receive the extended ends 3 and lugs 4 of the rack attachingmechanism, while the bearing grooves 10 are adapted to receive thepintle's of said attaching mechanism, said pintles being pivotallyengaged with the grooves whereby the racks may be swung outwardly at asuitable angle to form supports for the papers engaged therewith and maybe swung upwardly to -vertical positions as clearly indicated in fulland dotted lines in Figs. 1 and 2 of the drawings. When the racks areswung upwardly to vertical positions as shown in dotted lines, atypewriter case may be readily placed over the racks and engaged withthe edges of the base board or member so that the latter may be employedin the usual manner for forming the bottom of the case or cover. Whenthe racks are swung outwardly to operative positions the outwardmovement thereof is limited by the engagement of the lugs 1 with theinclined upper walls 9 of the recesses 8 as clearly shown in Fig. 2 ofthe drawing.

The extended ends of the rack frames are held in operative engagementwith the notches 7 and the pintles 5 are held in pivotal engagement withthe grooves 10 by sheet metal clips 11 which are enga ged with the edgesof the base board over the notches and grooves therein as shown. Theclips 11 are secured to the board by screws or other fastening devicesand in the upper and outer sides of the clips are formed notches 12through which the ends 3 of the rack 7 frames pass and which permit saidframes to be swung to operative and inoperative positions in the mannerdescribed. In the lower sides of the clips 11 and below the recesses 8are upwardly projecting detents 13 which are preferably formed bystriking up or indenting the metal forming the lower sides of the clips.The detents when thus constructed and arranged are disposed in the pathof movement of the lugs 1 on the extended ends 19 of the rack frames sothat when said frames are swung upwardly and inwardly to inoperativeposition the lugs 4 will spring over the detents 13 which will hold theracks in their vertical or inoperative positions.

When the racks are employed in connection with low typewriters or wherethe racks are of greater width than the height of the casing or cover ofthe typewriter it is necessary to remove the racks before applying thecase, and in order to permit this removal of the racks a slightlydifferent attaching mechanism is provided which necessitates a slightlydifferent construction and arrangement of the frame receiving notchesand bearing grooves in the base member or board. This modifiedarrangement of the notches and bearing grooves in the base member andthe modified construction of the attaching mechanism for the racks isclearly shown in the last five figures of the drawings. By reference tothese figures it will be seen that the ends of the racks are providedwith extensions 14 corresponding to the extensions 3 shown in the firstform of the invention and which have secured to their lower ends acombined stop lug 15 and pintle 16. The pintle 16 extends at rightangles to the extension 14 and may project inwardly therefrom as shownin Fig. 9 of the drawing or may project outwardly in the oppositedirection as will be readily understood. It will also be obvious thatthe attaching member of this form of the invention may be constructed asshown in Fig. 10 of the drawings to provide a pintle 17 projecting fromboth sides of the extension 14, which, in this instance, is bent aroundthe pintle midway between the ends thereof and is then extendeddownwardly to form a stop lug 18 which corresponds to the stop lug 15 ofthe form shown in F ig. 9. In either of these forms of the attachingmechanism the pintle member is soldered, welded or secured to theextension 14 in any suitable manner.

In Fig. 11 is shown a modification of the form and arrangement of theextension, pintle and stop lug shown in Figs. 7 and 9. In theconstruction of these parts as shown in Fig. 11 the extension 1% is bentupon itself to form a stop lug 15' and is then bent laterally at rightangles to form a pintle 16. By this arrangement it will be seen that theextension, lug and pintle are all formed in tegral with the ends of theracks, similar to the arrangement shown in Fig. 3 of the drawings. Thebase board or member for this form of the invention has formed thereinat suitable points, vertical notches 19 the lower ends of whichterminate in an inwardly extending recess 20 having an inclined upperwall 21 somewhat similar to the notch and recess shown in the first formof the invention except that the recess 20 is of greater height than therecess 8 and the inclined upper wall thereof extends to the upper end ofthe notch 19 as shown. In the upper side of the board or base memberadjacent to and extending from one or both sides of the notch 19 is abearing groove 22 the inner end of which communicates with the notch 19as clearly shown in Fig. 8 of the drawings. The bearing groove 22corresponds to the bearing groove 10 in the first form of the inventionand is provided to receive the pintles 16 and 17 of the attachingmechanism shown in Fig. 9 or that shown in Fig. 10. It will beunderstood of course that for the attaching member shown in Fig. 10 thegroove 22 will necessarily be formed on both sides of the notch 19.

When the last described form of the rack is applied to the baseboard theextended ends 14 of the racks are engaged with the notch 19 while thestop fingers 15 or 18 at the lower ends of said extensions will engagethe recesses 20. When thus arranged the pintles of the attachingmechanism will pivotally engage the recess 22 thus permitting the racksto be swung outwardly to an operative position. lVhen the racks are thusswung outwardly the stop lugs 15 or 18 as the case may be are broughtinto engagement with the inclined upper walls 21 of the recesses 20 thuslimiting the outward movement of the racks and supporting the latter inoperative positions. When it is desired to remove the racks it is simplynecessary to swing the latter upwardly to a vertical position as shownin dotted lines in Fig. 7 of the drawing, whereupon the racks may belifted and the pintles and stop lugs thereon disengaged from the grooves22 and notches 19 thereby entirely separating the racks from the basemember.

In the last form of the device the outer ends of the notches 19 arecovered by metal clips 23 which are constructed somewhat similar to theclips 11 shown in the first form of the device except that the uppersides of the clips 23 are cut away or recessed for a suitable distancebeyond the notches 19 as shown at 24 and have in their outer sides andin line with the notches 19 short notches 25 which permit the extensions14L on the ends of the racks to swing outwardly when the latter arearranged in operative positions. The upper sides of the clips when cutaway in the manner described permit the pintles on the extensions 14 tobe readily disengaged from the grooves 22 when the racks are removed.

, From the foregoing description taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be more readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is:

1. The combination with a base member having notches in one side edge,of a rack frame having its ends extended to form notch engaging membersadapted to be inserted into the notches of said base member, pintles onsaid notch engaging members having a pivotal engagement wlth said basemember, stop lugs on said notch engaging members, clips secured to theedges of the base member over the notches therein, and detents formed insaid clips and adapted to be engaged by said stop lugs when the rackframe is swung inwardly and upwardly to operative position.

2. The combination with a base member having in its side edgesvertically disposed notches communicating at their inner ends withrecesses having inclined upper walls and bearing grooves communicatingwith said notches, of rack frames having their ends extended to formnotch engaging members adapted to be inserted into the notches of saidbase member, pintles on said notch engaging members and having a pivotalengagement with the bearing grooves in said base member, stop lugsformed on said notch engaging members and adapted to be swung intoengagement with the inclined upper walls of said recesses, clips securedto the edges of the base member over the notches therein and detentsformed in said clips and adapted to be engaged by said stop lugs whenthe rack frames are swung inwardly and upwardly to operative positions.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
